Question

BlackTom AI · Accepted Answer

To analyze the question, consider what historical action actually stopped the Kuru outbreak among the Fore people of Papua New Guinea.
Option 1: the imposition of a ban on a historical cultural practice. This is correct because Kuru spread through ritualistic endocannibalism during mourning practices; once these rituals were banned by authorities, transmission declined and the outbreak ended.
Option 2: the eradication of a bat vector. This is incorrect; Kuru is a prion disease transmitted through human-to-human cannibalism, not through a bat vector or animal reservoir.
Option 3: proper sanitation. While sanitation is broadly beneficial for disease control, Kuru’s transmission route was cultural and direct contact during cannibalistic rites, not a sanitation-related pathway, so this does not explain the halt.
Option 4: the development of a vaccine. There is no vaccine for prion diseases like Kuru, and vaccination did not play a role in ending this outbreak; the cessation was due to stopping the ritual practice rather than biomedical intervention.
